TANNING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 508,281, `datedNovember '7, 1893.

Application filed March 27, 189s.

To all whom it may concern:

.Be it known that I, FRANoIs CHAILLY, a cltlzen of the United States,residing at Chicago, in the county of Cook and State of Illinols, haveinvented certain new and useful Improvements in Tanning Apparatus; and Ido hereby declare the followingto be a full,

ybe referred to hereinafter.

clear, and eXact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My lnvention relates to certain improvements 1n tanning apparatus andhas for its obgect the provision of an apparatus by the use of which theprocess of tanning as ordinarily carried out may be facilitated all aswill be hereinafter fully set forth.

The novel features of my invention will be carefully defined in theclaims.

In order that my improvements may be the better understood, l haveillustrated in the accompanying drawings an apparatus constructedaccording to my invention,in1which drawings--` Figure l is a verticalaxial section through the tan vat showing my improved apparatus 1n placefor use. Figs. 2 and 3 are enlarged detail views of portions of theapparatus to I n the views A is a tank in the bottom of which isarranged a bearing a, aligned with avslmilar bearing a in the ceiling 0cof the room. In these bearings is mounted a vertic'al shaft B, bearingat a point just below the liquor level of the vat A a fixed clutchsleeve b wlth which engages when the parts are in operative position, amovable clutch sleeve C, slidingly mounted after the manner of arunner,kon the shaft B. This movable clutch sleeve is provided about itsperiphery with a series of radial arms c having sharpened or pointedends c whereon the hides ory pelts are hung at the beginning of theoperation as represented by dotted lines'in Fig. 1.

Mounted on the upper end of shaft B near the'ceiling is a bevel gear cwhich gears with a pinion f on a countershaft g mounted in suitablebearings on the ceiling andpr'ovided with an idler pulley h and tightand loose pulleys h', '72,. y

The operation is as follows: The hides or pelts having been properlyprepared for treatment are provided with short slits or perfora- SerialNo. 467,854. (No model.)

tions in the hinder portion which slits are threaded over the sharpenedends of the rods c so that the pelts han g perpendicularly therefrom asseen in Fig. l. The several rods c being each provided with a pelt, themovable clutch sleeve C is lowered from the position seen in dottedlines in Fig. l until it comes into engagement with the fixed sleevebafter which the belt is shifted so asto rotate the shaft B. 'Thisrotation is continued at a speed of from thirty to eighty revolutionsper minute. for say a half hour or an hour and then the driving belt isreplaced by a crossed belt so that the revolution of shaft B will becontinued in a reverse direction for an equal time. This operation iscontinued until the hides have been thoroughly tanned after which themovable sleeve C is lifted from its engagement with the fixed sleeve band the hides removed.

In Fig 3 I have shown an enlarged fragmentary end view and elevation ofa modified form of the rod c, consisting of a stationary bar or stripcof angle iron to which is hinged a movable bar i of similar material.The bar c is provided along its lower edge with a series of teeth orhooksj and the bart' is provided with a corresponding series ofapertures i. Thus it will be seen that when the edge ofl the pelt isinserted between the two bars or strips and the same are shut togetheras seen in dotted lines the pelt wil'l be perforated and held fast tothe movable sleeve C.

From this it will be seen that my invention is invention, I

mounted therein, a collar longitudinally mov,

able along said shaft and a series of arms mounted. on said collar andadapted to support the pelts to be tanned, substantially as set forth.

2. Inl a tanning apparatus, the combinationrwith a vat, of a verticalshaft rotatively mounted therein, a clutch sleeve fixed to said shaft, amovable clutch sleeve mounted on IOO 1o said shaft and adapted to engagesaid fixed sleeve a series of radial arms on said nl ovable clutchsleeve, and means for clamping the pelts on said arms, substantially asset forth.

In testimony whereof I ax my signature in x 5 presence of two Witnesses.
